ПРОДУКЦИЯ описание: DW-EDFA55O The wild type optical fiber amplifier can use 220V or 60V AC and DC three 48V power supply mode, is suitable for field installation. Because it does not need the room, completely solve some outlying areas to build indoor room engineering problem. Cable route can take a shortcut, convenience for engineering design and construction, greatly reducing the network construction cost, maintenance cost and operation cost. Outdoor optical amplifier technology index and the same rules of the interior the same model, built in large power electronic hot and cold, so that the equipment can work at - 40 DEG C to 60 DEG C in field environment. This machine adopts the large cast aluminum shell, switching power supply with high performance, advanced lightning protection system, to ensure that the equipment can work stably for a long time in the wild environment.
